And yes, cam is in correct way, it has to be in order to install the pamco
thats not what I asked you Matt I asked you if the threaded end of the camshaft is at the RH side of the engine when you are sitting on the bike. If the camshaft is reversed the pamco
will still fit on the camshaft but it will be on the
wrong side of the engine. Depending on where on the cycle you had the crankshaft when you marked TDC your timing could still be out.
If you are getting a backfire and nothing else when using ether.... then your timing is out .
You have fuel and air you have compression and you say you have a spark. If it still won't start then that can only mean that your camshaft and crankshaft are not correctly aligned when at TDC or your camshaft sprocket is set wrong (very possible) or your spark is occurring at the wrong time in relation to your crank and cam cycle.
Forget the alignment pips and marks they are of no use to you if your cam sprocket is misaligned on the camshaft or you haven't marked TDC correctly. Work from first principles .
Check that the crankshaft is at TDC on the compression cycle on the left hand cylinder.
Check that both rockers are loose on the LH cylinder only .
Don't just eye up the valve stems and the cam lobes because the gaps are too small to see. Check the tappets are loose with your fingers.
Turn the crank until the piston in the RH cylinder is at TDC on its compression stroke (put your finger over the spark plug hole)
Check that both tappets are loose on the RH cylinder only.
if this checks out ok and you are using ether, then the engine should definitely fire and attempt to start otherwise you do not have a spark at the correct time in which case that will just leave the pamco setup to check. If you check for a spark, make sure that the spark plugs are grounded at all times or you risk damaging the pamco. Easiest way to do this is to clamp the spark plug bodies to a clean ground using mole grips .
what does this mean ?
